A former High-Ranking Army Officer turned Politician has been assassinated in France and when DGSE investigates his murder they find out that it is linked to the notorious Mafia with the Godfather being identified as Giovanni Riccolo. Going deeper into the investigation DGSE finds out that it is more widespread and it has come to knowledge that Giovanni Riccolo & his Mafia group want to take over the world and rule it with an iron fist. At first DGSE begin to believe that Riccolo is based in the USA and enlist the assistance of both DGSE (Q) & Canadian Intelligence. Together the two Intelligence services take down the Mafia bases around the USA however, they are still yet to find Giovanni Riccolo. Then by chance Guillaume eventually finds out that the Mafia Godfather is hiding out in London, England. Upon hearing this both DGSE & DGSE (Q) Agents are immediately ordered to go to London, England to terminate Giovanni Riccolo & the Mafia. In particular Guillaume is especially ordered to go on the mission as he was born in London. However, Guillaume becomes reluctant to go as he is a wanted serial killer in England but, eventually by force he is persuaded to go. To make things worse, Guillaume then finds out that Scotland Yard Police has appointed a Special Investigator to reopen the case of the murders of the pupils & teachers of his old school. This makes the mission more & more difficult for Guillaume as he has to keep looking over his shoulder. The only question is can Guillaume Moreau keep it together?
